September 10, 1963
Twenty black students entered public schools in Birmingham, Tuskegee and Mobile, Alabama. The Gov. George C. Wallace had ordered Alabama state troopers to stop the federal court-ordered integration of Alabama’s elementary and high schools. Pres. John Kennedy responded by calling out the Alabama National Guard to protect the students and to see the order enforced.
Pres. Kennedy spoke that day at American University’s commencement, saying,"Peace need not be impractical, war not inevitable . . . There is not peace in many of our cities because there is not freedom."
